Well, I (respectfully) disagree. Every time someone new gets in the car, they start making a playlist and halfway through it they erase it by accidentally not doing a long press, no matter how much I warn them about it. They then give up and go with the random shuffle, which isn't what they want, but it's easy. There are three other people in this thread saying they have the exact same problem... I don't see how a down press that used to mean play leading to a menu that says "play" as the first choice would be confusing at all...
I suspect this is somewhat a personal thing, as I always immediatly change winamp's default to enque, as I always want to build a playlist, but I still say the current method causes many people problems on a frequent basis.
